What would be your first step in solving -3x > 0?
A. multiply both sides by -3 and flip your sign
B. divide both sides by -3 and flip your sign
C. multiply both sides by 3 and flip your sign
D. divide both sides by 3 and flip your sign
Answer:
I would divide both sides by -3 then flip your sign since it is a multiplication equation in -3x which means you have to isolate it to find x.
Answer:
D
Step-by-step explanation:
You divide both sides by 3 and then you flip the sign.
Look at the cube, and the net of this cube. What is the surface area of this cube? Cube with one side labeled 16 feet. Net of the same cube also shown with one side labeled 16 feet.
Answer:
[tex]486[/tex] [tex]in^2[/tex]
Step-by-step explanation:
we know that
The surface area of the cube is equal to the area of its six square faces
so
[tex]SA=6b^2[/tex]
where
b is the length side of the cube
we have
[tex]b=9[/tex] [tex]in[/tex]
substitute
[tex]SA=6(9)^2=486 in^2[/tex]

Step-by-step explanation:
Step 1: Define
Identify given.
[tex]\displaystyle \lim_{x \to \infty} \frac{-4x^8 + x^3 - x + 7}{x^4}[/tex]
Step 2: Evaluate
[Limit] Simplify:Recall that infinity in the denominator converges to 0. Therefore, we can focus on the first part:
[tex]\displaystyle \begin{aligned}\lim_{x \to \infty} \frac{-4x^8 + x^3 - x + 7}{x^4} & = -4(\infty)^4 + \frac{1}{\infty} - \frac{1}{(\infty)^3} + \frac{7}{(\infty)^4} \\& = -4(\infty)^4 \\& = -4(\infty) \\& = \boxed{- \infty} \\\end{aligned}[/tex]
∴ we have found the limit to equal negative infinity.

When two straight lines or rays intersect at a shared endpoint, an angle is generated. The exact number of points at which the two rays will intersect is 1. The correct option is C.
What is an angle?When two straight lines or rays intersect at a shared endpoint, an angle is generated. An angle's vertex is the common point of contact. Angle is derived from the Latin word angulus, which means "corner."
As per the definition of an angle, the point at which the two of the given rays will intersect each other is exactly 1 point.
Hence, the exact number of points at which the two rays will intersect is 1.

A box and whisker plot—also called a box plot—displays the five-number summary of a set of data. The five-number summary is the minimum, first quartile, median, third quartile, and maximum. A vertical line goes through the box at the median. The whiskers go from each quartile to the minimum or maximum.
Here in the the box and whisker plot data values are not marked and these based on five points so mean cannot be determined here because mean required marked values.
The mean formula is given as the average of all the observations. It is expressed as Mean = {Sum of Observation} ÷ {Total numbers of Observations}.
But here in box and whisker plot no actual values are known so we can't find the mean.
Hence mean cannot be determined here with that given data.

For 1.8 hours, Layla drove her car east at a constant velocity. In this time, she drove 99 kilo meters and passed a motorcycle that was driving at 45 kilo meters per hour. What was her car's velocity?
Write your answer as a whole number.
kilo meters per hour to the east
Answer:
55 km/hr
Step-by-step explanation:
speed = distance / time
distance = 99 km
time = 1.8 hours
velocity = 99 km/ 1.8 hours= 55 km/hr
since distance is to the east, the velocity is also to the east

The cost for the contractor to have all the dirt hauled away for a foundation of 12 feet long, 9 feet wide and 6 feet deep is $720
Volume of rectangular prism
volume of a rectangular prism = lwh
where
l = lengthw = widthh = heightTherefore,
l = 12 ft
w = 9 ft
h = 6 ft
volume of the foundation = 12 × 9 × 6
volume of the foundation = 648 ft³
Therefore, the contractor pays $180 per load for the trucks remove the dirt.
648 cubic feet = 24 cubic yard
6 cubic yards = 1 truck load
24 cubic yard =

Question 5. Bob Orleans invested $3,000 and borrowed $3,000 to purchase shares in Verizon Communications. At the time of his investment, Verizon was selling for $47 a share.
o If Bob paid a $30 commission, how many shares could he buy if he used only his own money and did not use margin?
o If Bob paid a $60 commission, how many shares could he buy if he used his $3,000 and borrowed $3,000 on margin to buy Verizon stock?
o Assume Bob did use margin and paid a $60 total commission to buy his Verizon stock. Also, assume he paid another $60 to sell his stock and sold the stock for $54 a share. How much profit did he make on his Verizon stock investment?
The number of shares could he buy is 63.19 and 126.38. Then the profit gained by Bob is $764.68.
What is the profit gained by Bob?
Bob Orleans invested $3,000 and borrowed $3,000 to purchase shares in Verizon Communications.
At the time of his investment, Verizon was selling for $47 a share.
If Bob paid a $30 commission, then the number of shares could he buy if he used only his own money and did not use margin.
[tex]\rightarrow \dfrac{3000- 30}{47}\\\\\rightarrow \dfrac{2970}{47}\\\\\rightarrow 63.19[/tex]
If Bob paid a $60 commission, then the number of shares could he buy if he used his $3,000 and borrowed $3,000 on margin to buy Verizon stock will be
[tex]\rightarrow \dfrac{6000 - 60 }{47}\\\\\rightarrow \dfrac{5940}{47}\\\\\rightarrow 126.38[/tex]
Assume Bob did use margin and paid a $60 total commission to buy his Verizon stock. Also, assume he paid another $60 to sell his stock and sold the stock for $54 a share. Then the profit will be
[tex]\rightarrow (126.38 \times 54 - 60) - (6000)\\\\\rightarrow (6824.68 - 60) - 6000\\\\\rightarrow 6764.68 - 6000\\\\\rightarrow \$764.68[/tex]

Mato is making a leather belt inlaid with beads. On the first day there were b beads on the belt. On
the fourth day, there were b³ beads on the same belt. There were 216 beads on the belt on the
fourth day.
How many beads were on the belt on the first day?
Answer:
6
Step-by-step explanation:
On the fourth day, there were b^3 beads and 216 beads on the belt, which means b^3 = 216. Taking the cube root of both sides, we have b = 6, which means there were 6 beads on the belt on the first day.

The sides of an isosceles triangle are28 ,28 ,10 and long. What is the area of the triangle?
Answer: Approximately 137.74977 square units
===================================================
Explanation:
We can use Heron's formula to find the area of a triangle when given all three sides.
First we need the semiperimeter
s = semiperimeter
s = (perimeter)/2
s = (a+b+c)/2
s = (28+28+10)/2
s = 33
Now we can compute the area of the triangle.
[tex]A = \sqrt{s(s-a)(s-b)(s-c)}\\\\A = \sqrt{33(33-28)(33-28)(33-10)}\\\\A = \sqrt{18975}\\\\A \approx 137.74977\\\\[/tex]
Val needs to find the area enclosed by the figure. The figure is made by attaching
semicircles to each side of a 46-m-by-46-m square. Val says the area is 1,206.12
m². Find the area enclosed by the figure. Use 3.14 for 1. What error might Val have
made?
Answer: See below
Step-by-step explanation:
Radius of the semicircle = 46/2 = 23 m
[tex]\therefore$ Area enclosed by the figure $=4 \times$ Area of semicircles + Area of square \begin{aligned} \\&=4 \times 3.14 \times(23)^{2} \times \frac{1}{2}+(46)^{2} \\&=3322.12+2116 \end{aligned} \\\\\\Area enclosed $=5438.12 \mathrm{~m}^{2}$[/tex]
So, Val might have have subtracted 2116 from 3322.12 instead of adding since 3322.12 - 2116 = 1206.12
